SLIDE SHOW

Actual ending

Thenali (played by Kamal Haasan) marries Janaki (played by Jyothika) sister of Dr Kailash (played by Jayaram). The final shot ends with a family group picture clicked by KS Ravikumar.

Alternate Ending

Now, presume there is a back story of Thenali being innocent. Thenali has actually come to capture the minds of the entire family, including Janaki, to take revenge against Dr Kailash as he would have spoilt Thenali's sister's life. So the film could end with Kamal thinking about this backstory and revealing his true side to the audience.
